“晨昏线”是《地球自转的地理意义》一节的难点内容,也是高一地理教材中一个典型的难点,教材中对这部分内容未加详细叙述,学生理解起来比较困难。讲授过程中如果能循序渐进地讲解,学生定能一步步攻克难点。 “Twilight Line” is a difficult point in the section “The Geographical Significance of Earth’s Rotation,” and it is also a typical difficulty in high school geography textbooks. The textbook does not give any detailed description of this part of the content, and students are more difficult to understand. If you can explain in a step-by-step manner during the lecture, students will be able to overcome difficulties step by step.
